wb- Thev Schedule referred to in theeLetters Patent and' making part of the same.

To all whom it ma/y concern.-

Be it known that I, ROBERT S. BOYD, of Smithland, in the county of Livingston, and State of Kentucky, have invented certain new andfuseful Improvements in Road-Scrapers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a portion of this specication, in which- Figure 1 is a side view of a scraper constructed according to my invention.

Figure 2l is a plan view of thesame.

Similar letters of reference indicate correspondng parts in vboth figures.

The object of this invention is to provide a scraper for repairing roads, and for other work of like character, which may be much more conveniently handled or manipulated when in use than those hitherto employed, and which will also perform its work in avery superior manner.

The invention consists inan oblique-scraping share, attached to a wheeled suspendingframe, in such manner, that by raising the rear end of such frame, the

aforesaid blade may be brought clearof the ground,

when desired; and in so combining a lever, cord, andv pulleys with the aforesaid wheeled suspending-frame, and the draught-pole by which the scraperis drawn, that the frame may be very readily operated to raise thescraping-blade, as just mentioned.

To enable others to understand the construction and operation of my invention, I will proceed to describe it with reference to the drawings.

' A represents an axle, furnished With'vtwo wheels, B, y

and having rigidly secured thereto a draught-pole, C, withinthe bifurcated inner end of which areV two grooved pulleys, a b.

Shown at D is a rectangular frame, pivoted at about one-third, more or less, of its length from its forward end, to the upper side of the axle A, as shown more fully at a'in fig. l.

Projecting upward from the rear end of the draughtpole, o r from the axle, is a standard, E, in the upper end of which is pivoted a lever, F. The long arm of this lever extends back to the rear of the frame D, while its,forwardly-extending short arm has attached 'to it a cord, c, which passes down underneath the pulleys a b, and thence upward to the forward endof the frame DI to whichit is attached.

Secured to" and underneath the rear portion of Athe frame just mentioned, by means of strong braces, d d is a scraping-share, G, which is placed obliquely, and with its surface inclined, as represented in the drawings, the said scraping-share being either wholly of metal, or of wood, with a metallic blade, e, vfixed to its lower forward or scraping-edge.

When the apparatus is drawn along, the frame D being lowered, the scraping-share is brought in contact with lthe ground, and the soilv or earth is scraped or acted upon thereby in a manner similar to that of an 4oblique scraper without Wheels, and is' thus evenly spread, and the surfaceof the ground or roadway, as

the case maybe, is thus smoothed and levelled; and

in case, for any reason, it is desired to elevate the scraping-share, the long arm of the lever F is pressed upon, the cord c pulls downward the forward, and of course raises -the rear end of the frame D, and thus elevates the scraping-share, as just mentioned.

What I claim as my invention, and desire to secure by Letters Patent, is-

- The combination of the frame D, hinged to the axle A, and carrying the oblique scraper G, with the lever F, standards E, cord c, and f pulleys a b, all arranged and operating substantially as shown and described. ROBERT S. BOYD.
